1.4 Checklists
The checklists serve as a reference for the machine manufacturer or supplier (see chapter 11 "Testing").
They replace neither testing of the complete machine or system prior to the initial start-up nor their periodic
testing by a competent person. The checklists contain minimum testing requirements. Depending on the
application, other tests may be necessary.

Safety
Leuze electronic GmbH + Co. KG RSL 420 9
2 Safety
Before using the safety sensor, a risk assessment must be performed according to valid standards (e.g.
ENISO12100, ENISO13849-1, IEC/EN61508, ENIEC62061). The result of the risk assessment deter-
mines the required safety level of the safety sensor (see chapter 15.1 "Safety-relevant technical data"). For
mounting, operating and testing, this document as well as all applicable national and international stan-
dards, regulations, rules and directives must be observed. Relevant and supplied documents must be ob-
served, printed out and handed to affected persons.
ÄBefore working with the safety sensor, completely read and observe the documents applicable to your
task.
In particular, the current version of the following national and international legal regulations apply for com-
missioning, technical tests and handling of safety sensors:
• Machinery Directive
• Low Voltage Directive
• Electromagnetic Compatibility Directive
• Use of Work Equipment Directive
• Directive on the restriction of the use of certain hazardous substances in electrical and electronic equip-
ment
• OSHA
• Safety regulations
• Accident-prevention regulations and safety rules
• Ordinance on Industrial Safety and Health and employment protection act
• Product Safety Law (ProdSG)
NOTICE
For safety-related information you may also contact local authorities (e.g., industrial inspec-
torate, employer's liability insurance association, labor inspectorate, occupational safety and
health authority).
2.1 Intended use
The safety sensor protects persons or body parts at points of operation, danger zones or access points of
machines and systems.
WARNING
A running machine may result in serious injury!
ÄMake certain that the safety sensor is correctly connected and that the protective function of
the protective device is ensured.
ÄMake certain that, during all conversions, maintenance work and inspections, the system is
securely shut down and protected against being restarted.
• The safety sensor may only be used after it has been selected in accordance with the respectively ap-
plicable instructions and relevant standards, rules and regulations regarding labor protection and safety
at work, and after it has been installed on the machine, connected, commissioned, and checked by a
competent person (see chapter 2.3 "Competent persons").
• When selecting the safety sensor it must be ensured that its safety-related capability meets or exceeds
the required Performance Level PLr ascertained in the risk assessment (see chapter 15.1 "Safety-rele-
vant technical data").
• The safety sensor may only be used in North America in applications that satisfy the requirements
specified by NFPA79.
• With the “access guarding” function, the safety sensor detects persons only when they enter the danger
zone but cannot tell whether there are any persons inside the danger zone. For this reason, a start/
restart interlock in the safety chain is essential in this case.
• The construction of the safety sensor must not be altered. When manipulating the safety sensor, the
protective function is no longer guaranteed. Manipulating the safety sensor also voids all warranty
claims against the manufacturer of the safety sensor.

Safety
Leuze electronic GmbH + Co. KG RSL 420 10
• The safety sensor must be inspected regularly by a competent person to ensure proper integration and
mounting (see chapter 15.1 "Safety-relevant technical data").
• The safety sensor must be exchanged after a maximum of 20 years. Repairs or the exchange of wear
parts do not extend the mission time.
CAUTION
Observe intended use!
The protection of personnel and the device cannot be guaranteed if the device is operated in a
manner not complying with its intended use.
ÄOnly operate the device in accordance with its intended use.
ÄLeuzeelectronicGmbH+Co.KG is not liable for damages caused by improper use.
ÄRead these operating instructions before commissioning the device. Knowledge of the oper-
ating instructions is an element of proper use.
NOTICE
Comply with conditions and regulations!
ÄObserve the locally applicable legal regulations and the rules of the employer's liability insur-
ance association.
2.1.1 Vapors, smoke, dust, particles
Vapors, smoke, dust and all particles visible in the air can cause the machine to switch off unintentionally.
This can mislead the user into bypassing the safety devices.
ÄDo not use the safety sensor in environments in which heavy vapors, smoke, dust or other visible parti-
cles occur at the beam level.
2.1.2 Stray light
Light sources can impair the safety sensor's availability. Interfering light sources are:
• Infrared light
• Fluorescent light
• Strobe light
ÄEnsure that there are no interfering light sources at beam level.
ÄPrevent reflective surfaces at beam level.
ÄWhere applicable, take protective field addition distances into account.
ÄImplement all additional measures to ensure that any special application of any effected beam types
does not impair the safety sensor's operation.
2.1.3 Obstructions in the protective field
ÄDo not bring any additional window materials into the area monitored by the safety sensor.
NOTICE
No screen between optics cover and monitoring area!
ÄBetween the optics cover of the safety sensor and the monitored area, no further screen
may be mounted to protect the safety sensor.
